Abstract: 1326865 Electromagnetic brakes; full-face disc brakes ZINSER-TEXTILMASCHINEN GmbH 15 March 1972 [19 March 1971] 12131/72 Heading F2E An electromagnetic brake for a shaft 14 rotatable in a shaft bearing 11 comprises a yoke 21 of magnetic material carrying a winding 23 and being adjusted to be secured to the shaft bearing 11. An intermediate member 24 is guided for rectilinear movement towards an armature 17 of magnetic material which armature is adjusted to be connected to the shaft 14. The intermediate member 24 comprises at least two portions 26, 27 of magnetic material and a portion 29 preferably of plastics material forming a braking surface for co-operation with the opposed surface of the armature 17. At least one of the two portions 26, 27 has a surface which extends parallel to its direction of momenent, the surface opposing a face of the yoke 21 so that on energization of the winding 23 poles are produced at these surfaces. Also on energization of the winding 23 unlike poles are induced at the opposed surfaces of the two portions 26, 27 and the armature 17 so that the intermediate member 24 moves towards the armature 17 to bring the braking surface into engagement therewith. In the construction shown the guidance of the intermediate member 24 is effected by pins 25 connected to the member and being housed in slots in the yoke 21. In further embodiments the outer periphery of the intermediate member extends beyond the outer periphery of the yoke and the guidance is effected by bent in portions of the antiperiphery of the intermediate member working in slots in the yoke (Fig. 2, not shown) or pins in the yoke working in slots in the intermediate member (Fig. 3, not shown). The movement of the intermediate member may be limited and the armature be movable towards but spring loaded away from the intermediate member, (Fig. 4, not shown). In its rest position the armature forms a coupling between the shaft and the driving means for the shaft but when the winding is energized the intermediate member moves towards the armature followed by a movement of the armature towards the intermediate member to disengage the drive from the shaft and bring the braking surfaces into engagement to effect braking of the shaft. The brake may comprise a plurality of electromagnets in which each braking surface extends parallel to the shaft.

Title: Phosphors and method of making the same
IPC: C09K11/77
Filed: 1966-03-22
Abstract: An alkaline-earth halophosphate phosphor is activated with monovalent copper and trivalent terbium, the ratio of each to the sum of alkaline-earth elements being 0.002:1 to 0.02:1 preferably 0.01:1 and 0.003:1 to 0.06:1 respectively, said alkaline earth elements being one or more of calcium, strontium, or barium, the halogen being chlorine, fluorine or a mixture thereof.  On increase of the terbium to calcium ratio, above 0.02:1 for example, the green terbium emission (peak 5450 <\>rA) predominates over the blue copper emission (peak 4800 <\>rA) under 2537 <\>rA and 3650 <\>rA U.V. radiation although the excitation spectra remains virtually that of the phosphor activated by copper alone. The phosphor, which also responds to cathode-ray excitation and X-rays, may be used in fluorescent and high pressure mercury lamps for instance, the emission being little affected up to 400 DEG  C.  In examples calcium, barium, fluorine, chlorine and terbium compounds are pulverized, mixed, fired between 110 DEG  to 1300 DEG  C., preferably 1180 DEG  to 1230 DEG  C. for 2 hours in a moist hydrogen-nitrogen atmosphere, the hydrogen to total gas mixture volume ratio being 1 to 20% preferably 2 to 5% (3% for instance).
